We confirm this problem with incorrect reposition of the frame window in 2.80, but it occurs only on some computers - not on any computer. Could you please send your test project to support@prof-uis.com?

I discovered this morning that the problem exists only when I click on the close button (crossbar) which is on the title bar. When using File/Close menu, it’s ok. Anyway, I have a simple sample (.exe and/or sources) if you want them. I’m using CExtPaintManagerOffice2007_R2_LunaBlue theme, Prof-UIS v2.80, XP pro.

We failed to see any location changes of the main frame window. Could you please send us a screenshot demonstrating the problem? Of course, if you demonstrate how to reproduce the problem using any of our samples, that would help us a lot..
